1: Atoms

This was a great Intro Journey on the basics of atoms. I really liked all the hands on activities that we do in class, and I have a lot of respect for Ramsey who puts all the experiments together. The first thing we learned about was what makes up an atom. We learned everything from the Protons and Neutrons in the Nucleus, to the valence electrons and their ground/excited states. In our first experiment, we tested which Ion made which color flame when burned. For example, when we burned Copper Ions, a green flame was produced. Next, we learned the difference between Atomic Mass and Molar Mass. I thought it was really interesting how I was never taught about measuring atoms in moles, because it's a big deal, and I'm glad I know now. When we studied mole conversion, I struggled in the beginning with the decimals and how small they were, but once I got enough practice, I could solve the equations quickly.
